Hi Simon<br>
<br>
I can confirm what Balz is saying, whereas I would emphasize
that it is mostly about flexibility.<br>
<br>
You can find some examples under "Deployment" of the
documentation:<br>

i was just reading <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://www.yanel.org/en/documentation/how-to-add-ssl-to-apache-httpd.html">http://www.yanel.org/en/documentation/how-to-add-ssl-to-apache-httpd.html</a>
and it seems to be a bit outdated , at least if you use an recent
linux distro where apache above 2.2.13. is bundled.<br>
then just enter<br>
<br>
apt-get install apache2<br>
<br>
sudo a2enmod proxy<br>
sudo a2enmod proxy_http<br>

<br>
I have update now<br>

accordingly.<br>

whereas I just realize that we need to replace the svn links by
git.<br>

<div><br>
</div>
<div>in larger enterprise setups there is always a web server
in front of the application server (tomcat, glassfish,
etc.).</div>
<div>there are many advantages for having a web server in
front of the app server:</div>
<div>- you can scale better (with plugins like mod_jk or alike
you can distribute the load over N application servers. Of
course, the plugin must support session stickyness, so that
request with the same session cookie gets forwarded to the
same app server.</div>
<div>- you can serve static content from the web server. this
way you have much less "noise" on the app server. Of course:
web server must have access to the content, so the
deployment model might look different, if web and appserver
are on physically different machines</div>
<div>- you can easily switch to a static maintenance page: you
configure the web server to show a certain page. during this
time, you can modify the app servers in the back end. if
done, you can go back to the normal configuration where
requests are routed to the app servers</div>
<div>- for highly secure applications, it's probably a must to
introduce a web server, as you can much better protect your
app server from unwanted requests (see for instance
"perimeter authentication")</div>
<div><br>
</div>
<div>downside of it is:</div>
<div>- you have more infrastructure to maintain</div>
<div>- more complex monitoring setup</div>
<div>- more expensive</div>
<div>- more complex support demand (if something goes wrong,
you have to analyze more)</div>
<div><br>

just wondering why yanel resp. tomcat is mostly deployed
behind an apache?<br>
what's the reason and does someone has experience in
using the tomcat without an apache web server in front?<br>
